Information About M9184D1021
The M9184D1021 is part of Honeywell’s trusted Modutrol IV Series 90 motor family, engineered for proportional control of dampers and valves in commercial HVAC systems. Operating at 24 VAC, it includes dual-ended shafts, quick-connect terminals, and an adjustable stroke range of 90° to 160°. This foot-mounted actuator is built for reliability, with fixed torque across the voltage range and options for auxiliary switches. It does not include a spring return, making it suitable for applications where powered return is not critical.
Key Features:
- Proportional Control: Accepts 135-ohm input signal for modulating performance.
- Adjustable Stroke: Field-configurable stroke from 90° to 160° for flexible damper or valve operation.
- High Torque Output: Provides a constant 150 lb-in of torque across the voltage range.
- Dual Shaft Design: Slotted and tapped on both ends for versatile linkage compatibility.
- Durable Housing: Weather-resistant NEMA 3 rating when mounted upright.
- Quick Connection: Standard quick-connect terminals for simplified wiring.
- Auxiliary Switch Ready: Supports optional field- or factory-installed auxiliary switches.
- Non-Spring Return: Maintains position on power loss — ideal for controlled HVAC zones.
The M9184D1021 delivers the torque, control precision, and field-adjustable configuration required for professional-grade damper and valve automation.
